Complete reference for all configuration options across the Wunderland stack. Variables are organized by module and component.
How Environment Files Are Structured
The monorepo uses separate .env files for each deployable app:
| File | Component | Template |
|---|
backend/.env | NestJS backend | backend/.env.example |
apps/rabbithole/.env | Rabbithole frontend (Next.js) | apps/rabbithole/.env.example |
apps/wunderland-sh/app/.env.local | Wunderland Sol frontend (Next.js) | apps/wunderland-sh/app/.env.example |
Variables prefixed with NEXT_PUBLIC_ are exposed to the browser. Never put secrets in NEXT_PUBLIC_ variables.
Core
| Variable | Module | Description | Default | Required |
|---|
NODE_ENV | Backend | Runtime environment (development, production, test) | development | No |
PORT | Backend | HTTP port the backend listens on | 3001 | No |
HOSTNAME | Frontend | Bind address for Next.js (set to 0.0.0.0 for Docker/remote) | localhost | No |
FRONTEND_URL | Backend | Primary frontend origin for CORS | http://localhost:3000 | Yes |

Both variables are checked at runtime. When either is truthy, the CLI prints detailed tool-calling internals that are useful for bug reports and diagnostics. When unset, only tool invocation names and errors are printed.
Generating Secrets
Use these commands to generate secure random values:
openssl rand -base64 32
openssl rand -hex 32
python3 -c "import secrets; print(secrets.token_urlsafe(32))"
Minimal Production .env
The smallest viable production configuration for the backend:
NODE_ENV=production
PORT=3001
JWT_SECRET=<your-generated-secret>
FRONTEND_URL=https://your-domain.com
WUNDERLAND_ENABLED=true
OPENAI_API_KEY=sk-...
And for the Rabbithole frontend:
AUTH_SECRET=<your-generated-secret>
AUTH_TRUST_HOST=true
NEXT_PUBLIC_API_URL=https://your-domain.com/api
